Although there is no evidence that microorganisms ever existed on Ceres, the results of a new study support theories that this dwarf planet may have once...
A protective atmosphere, a friendly Sun, and lots of liquid water — Earth is a special place. Using the unprecedented capabilities of the NASA/ESA/CSA...
This planet candidate, Alpha Centauri Ab, could be a gas giant, orbiting 1 to 2 times the distance between Sun and Earth, according to two papers to be...
Radiolysis induced by Galactic cosmic rays could provide a viable energy source for microbial metabolism in the subsurface environments of rocky planetary...
In their new paper, Los Alamos National Laboratory planetary scientist Nina Lanza and colleagues looked at what would be needed to make the surface environment...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected the chemical fingerprints of dimethyl sulfide (DMS) and/or dimethyl disulfide...
A team of biologists from the United States, Canada, the United Kingdom and France has developed a scenario of what life on Titan, Saturn’s largest moon,...
Called ferrihydrite, this iron mineral formed during a cold, wet period on early Mars under oxidative conditions, followed by a transition to the current...
Using data gathered by China’s Zhurong rover, planetary researchers have identified hidden layers of rock under the Martian surface that strongly suggest...
White dwarfs may present amenable environments for life on planets formed within or migrated to their habitable zones, generating warmer surface environments...
One of these exoplanets, HD 20794d, is likely to be a rocky planet in the habitable zone of its parent star, the G-dwarf HD 20794.
This image shows the...
In a new paper, planetary researchers from Texas A&M University and the University of Washington introduce a new thermodynamic concept called the centotectic...
Planetary researcher Tereza Constantinou and her colleagues at the University of Cambridge have examined the chemical composition of the Venusian atmosphere...
Scientists from Curtin University and the University of Adelaide have analyzed a 4.45-billion-year-old zircon grain from a famous Martian meteorite called...
On Earth, solar radiation can transmit down to multiple meters within ice, depending on its optical properties. Organisms within ice can harness energy...
One-third of Mars’ surface has shallow-buried water, but it is currently too cold for use by life. Proposals to warm Mars using greenhouse gases require...
Ocean worlds are planetary bodies that have a liquid ocean, often under an icy shell or within the rocky interior. In our own Solar System, several moons...
Despite its Earth-like size and source material, Venus is extremely dry, indicating near-total water loss to space. Using computer simulations, planetary...
